DC - Educational Institution

Educational Institutions comprise educational facilities like kindergartens, primary/secondary schools, polytechnics, junior colleges, institutes of technical education, training institutes, universities, foreign and special schools (eg school for the disabled). They are primarily for educational purposes and are zoned “Educational Institution” (EI) in the Master Plan.

For planning purposes, dancing schools, computer schools, tuition centres are treated as commercial schools. As such, they are zoned “Commercial” in the Master Plan. Commercial schools and tuition centres are therefore not allowed in EI zone.

The planning parameters and guidelines here are applicable to all EI developments except for special education schools which have different requirements given the nature of the use. The detailed parameters for special schools are under the tab Special Education Schools.

Special education schools provide training for the disabled aged 1 – 18 years old. Special education schools may be classified as:

• Ambulatory: these schools are for the mentally challenged, visually handicapped, and the hearing impaired.

• Non-ambulatory: these schools are for the orthopaedic impaired or multi-handicaps.

Conversions of properties to special education schools are evaluated depending on merits. Purpose-built special education schools are allowed on land zoned “Educational Institution”.

All parameters and considerations applicable to other EI developments shall apply to special education schools except for those listed below.

The allowable GPR for special education schools is 0.5 (minimum).

The allowable number of storeys for ambulatory schools is 4 (maximum). The allowable number of storeys for non-ambulatory schools is 2 (maximum).

The actual number of storeys allowed may vary, depending on the site topography and the context of the surrounding area.

The allowable floor-to-floor height for special education schools is 5.0m (maximum).

For mixed ambulatory and non-ambulatory school, the non-ambulatory facilities shall be sited on the lower floors to facilitate easier movements for the students.

A students’ hostel or dormitory is used for lodging by students unrelated by blood, marriage, adoption or legal guardianship. The premises are considered as students’ hostel if:

• The total number of students staying in the premises exceed 6 students; and

• The premises is for accommodation facilities for full time students studying in the local primary schools, secondary schools, junior colleges and tertiary institutions.

Students’ hostels may either be ancillary to the EI development, for eg as a separate dormitory building that serves students/staff of the school or independent developments.

Students’ hostel developments may be allowed on sites zoned Educational Institution, Commercial/Residential and Residential with 1^st storey Commercial.

Independent students’ hostel developments may also be allowed on sites zoned Residential provided that:

• The site shall not be located in estates safeguarded for landed housing only (eg Good Class Bungalow Areas);

• The site shall be located at the fringe of non-landed residential estates and in street blocks which already have non-residential uses;

• The site shall be fronting a category 2 or 3 road; and

• The amenity of the surrounding areas shall not adversely affected.

Conversion of existing flats to students’ hostel may be either on an en-bloc or a ‘per floor’ basis. Conversion on a ‘per floor’ basis (ie all the flat units on the same floor sharing a common staircase or lift access) may be considered only under a single Temporary Permission (TP) regardless of the number of owners involved, provided that it does not result in dis-amenity to other residents.

The students’ hostel shall be located below existing residential floors to minimize potential inconveniences and disturbances to the residents.

All owners shall submit a Letter of Undertaking (LOU) that the students’ hostel will be run by a single operator. For conversions on a per floor basis, all owners on the floor are to sign the LOU. A fresh LOU shall be submitted for subsequent renewals of the TP.

The allowable Gross Plot Ratio (GPR) and number of storeys for the EI shall take into account the character of the surrounding area. As a guide, depending on the allowable GPR, the corresponding number of storeys are shown in the table below. The actual number of storeys allowed may vary, or be higher, depending on the site topography, site condition and the context of the surrounding area. 

Basement storeys that protrude more than 1.0m above ground level on any side shall be counted as a storey.

For redevelopment of an existing approved EI or to carry out major extensions to it, the proposed increase in GPR or GFA is subject to planning consideration taking into account the location of the EI, context of the surrounding area and requirements of other government agencies. Planning approval from URA shall be obtained first before commencement of works.

Allowable Gross Plot Ratio and Storey Height

Unless otherwise stated, the overall building height¹ of EI developments is subject to compliance with the technical height controls of the relevant agencies such as Civil Aviation Authority of Singapore (CAAS) and the Defence Science and Technology Agency (DSTA).

¹ Building height is based on Singapore Height Datum (SHD). 

The maximum floor-to-floor height of EI developments is 5.0m.

Predominant Sky Terrace Storeys (PSTS) are floors where the sky terrace areas within the 45-degree line occupy at least 60% of the floor plate. 

If the proposed number of storeys in the development is more than 7 storeys, EI developments with PSTS may be allowed additional building height depending on the number of storeys proposed as shown in the table below:

Additional Building Height based on Proposed Storey Height

The additional building height may only be distributed to the sky terrace floors within the development. Spaces for M&E services located directly beneath the sky terrace floor may be included in the additional height.

The overall building height is subject to technical height controls.

The additional building height shall not apply to:

1. Developments within Conservation Areas and sites with National Monuments;

2. Developments with height control of 6 storeys or less; or

3. Developments with special controls e.g. areas with street block plans.

In addition to (a) – (c), any additional building height will be subject to evaluation for developments adjacent to conserved buildings or in urban design areas with site-specific height considerations.

The Bonus GFA scheme applicable to Educational Institution is: 

Refer to section on POPS.

The scheme aims to encourage building owners to adopt either DCS or CCS for their building. This could be by collaborating with other building owners to establish new DCS or CCS networks, or tapping onto an existing DCS or CCS network in the area.

Host buildings in DCS and CCS networks will need to set aside spaces for the district cooling plant and chiller plants respectively to serve the larger network. Such Mechanical and Electrical (M&E) spaces needed to support the DCS/CCS network will be allowed as bonus Utility GFA, over and above the Master Plan allowable GFA for the site. The additional Utility GFA may be subject to payment of Land Betterment Charge (LBC), if any.  

For CCS networks:

• If the host building’s original in-building chiller plant (IBCP) spaces are computed as GFA, these can then be computed as bonus Utility GFA. The freed up GFA from the original IBCP can be put to other uses in the development. 

• If the host building’s original IBCP spaces are exempted from GFA¹, bonus GFA equivalent to the size of the IBCP room will be allowed over and above the Master Plan allowable GFA for the site. Bonus GFA may be subject to payment of LBC based on its proposed use.

The DCS/CCS-related M&E spaces may also be considered for GFA exemption if the spaces fulfil the respective criteria of the prevailing M&E-related GFA exemption schemes. 

¹Applies to IBCP spaces within the building envelope that were previously granted GFA exemption based on the relevant GFA exemption provisions. Does not apply to open-to-sky IBCP spaces (e.g. on the rooftop)

Submission requirements

The following information / documents are to be furnished to URA as part of the development application (DA): 

Developments receiving chilled water from the host building(s) in a DCS/CCS network benefit from not having to provide their own in-building chiller plant (IBCP) systems. The following GFA incentives are applicable for such receiving developments:

Submission requirements 

The following information / documents are to be furnished to URA as part of the development application (DA):

The following types of developments will not be eligible for the GFA incentives:

• Existing buildings that are already connected and part of a DCS/CCS network, as the GFA incentives will not retroactively apply to such buildings.

• Where it is a mandatory requirement for the development to adopt DCS/CCS (e.g. as part of conditions of tender in Government Land Sales sites). 

Specific to receiving developments who wish to tap onto an existing DCS/CCS network, the following criteria are to be met before the GFA incentives will apply:

• The receiving development was originally approved at a time when there was no operational DCS/CCS network in the area; or

• The receiving development shall be a minimum age of 10 years¹ (from date of original TOP).

Where necessary, the bonus GFA may be approved on temporary basis for monitoring purposes of this new scheme.

¹ This is the average lifespan of an IBCP system. The intent is to discourage the premature decommissioning of IBCP systems of newly completed buildings. Owners of newer buildings can instead consider switching to DCS as part of their planned IBCP replacement cycles (i.e. after 10 years).

All EI developments shall be sufficiently set back from the road and common boundary. The setback distance is measured from the road reserve¹ line or boundary line to the external wall of the buildings, excluding land to be vested to the State for road or drainage or public purpose.

All EI developments fronting a public road shall provide a road buffer, the width of which depends on the hierarchy of the road. A green buffer shall be set aside in the road buffer depending on the width of the road buffer.

The buffer requirements for the Road Categories 1 to 5 are in Table 1 below. The common boundary setback requirements are in Table 2 below. Different setback requirements may apply for sites within the Geylang area or the Central Area, both of which are guided by Urban Design guidelines.

¹ Road Reserve: The plot of land to be vested in the State as required under the Street Works Act. It is demarcated by the line of Road Reserve in the Road Line Plan and the site boundary.

A basement storey refers to a storey of a building which may be partially or wholly below the existing ground level. In so far as storey height control is concerned, basement storeys that protrude more than 1.0m above ground level on any side shall be counted as a storey. 

The physical limit for which the basement may be built up to is shown in the table below.

Basement Setback

¹ Road Reserve: The plot of land to be vested in the State as required under the Street Works Act. It is demarcated by the line of Road Reserve in the Road Line Plan and the site boundary.

Basements with vertical openings on the side walls may be allowed only if they are required for natural ventilation and to meet the building regulations. The guidelines are as follows:

• While the protrusion measured from the level at the site boundary shall not exceed 1.0m, basements may be exposed up to 2.0 m from the point where the platform level meets the basement wall (ie the earth around the basement wall may be cut to slope down to achieve the 2.0m basement exposure with openings).

• The extent of the slope within the green buffer or planting strip shall have a gradient of 1:2.5.

• Vertical cutting of the earth resulting in a trench around the basement is not allowed.

• The extent of the vertical openings or the types of cover over the vertical openings shall be subject to the requirements of the other technical departments.

• Horizontal openings to the basement are allowed within the setback distance outside the green buffer and planting strip, subject to provision of effective screening to hide the view to the basement.

  

Special and Detailed Control Plans (SDCP) provide detailed guidelines for specific areas. The SDCPs may be viewed here.

The following areas may be subject to security screening requirements. URA will confirm this upon submission of a proposed development.

Qualified Persons (QPs) should consider the screening requirements in the early stage of their planning and design to avoid abortive work subsequently.

Where security screening is deemed necessary, it shall consist of permanent fixtures that are difficult, if not impossible to remove. The following screening measures may be considered:

Residential units and common areas may be screened where necessary with blank walls, external concrete/metal fins, or the building may be re-orientated such that the windows¹/openings/balconies do not have direct view towards the protected area.

¹ Window: Raised openings that are at least 0.9m above the floor slab. They are intended to provide ventilation and lighting, and not for access. Full height windows and windows that are lower than 0.9m that can potentially be used as access points will need to be highlighted in the submission plans for URA’s evaluation and approval.

The parapet wall at the rooftop shall be at least 3m high and access to the rooftop from a public area shall be secured by a lockable door/hatch. The door/hatch may be electronically linked to an alarm system monitored by the building management.

Street block plans guide the detailed setback, storey height and building height, for the following locations. Click on the reference links to view the detailed street block plan.

Guidelines on Urban Design (UD) intentions are to preserve and enhance the urban character of the different planning areas. They help to ensure that developments integrate well with their surrounding urban environment.

Developments in Central Area and Key Growth areas (such as Jurong Gateway, Paya Lebar Central, Punggol Digital District and Woodlands Central), may be guided by specific urban design requirements, where the planning intention is to introduce activity generating uses. These urban design requirements shall take precedence over the standard development control parameters.

Refer to URA SPACE for the Urban Design Guidelines Plan and designated AGU areas.

AGUs help to activate and enliven streets; contributing to its vibrancy, providing key basic amenities, and attracting visitor-ship to the precincts. The following situations may require AGUs:

1. Urban Design Areas shown in the Special and Detailed Control Plan (SDCP) Street Block and Urban Design Plan;

2. Government Land Sale (GLS) sites where AGUs are required as part of the Technical Conditions of Tender;

3. Sites that undergo redevelopment or major A&A works and where AGUs are required as part of the planning conditions issued for these works;

4. Other areas as directed and specified by the Competent Authority.

AGUs may be required to be provided in the following typical locations:

1. 1^st storey of developments fronting key streets, pedestrian malls, through block links, and public spaces;

2. Alongside underground pedestrian links (UPLs) at the basement levels of the developments;

3. Alongside elevated pedestrian links (EPLs) at the 2^nd storey of the developments.

The proposed AGUs in the above locations are to be assessed contextually, taking into account the planning intention for the area and potential amenity problems that will impact on the surrounding developments. Uses not allowed are those that do not directly contribute to street vibrancy and/or can potentially cause amenity problems to neighbours.

Example of uses that may be considered as Activity Generating Uses (AGUs) are:

• Shop

• Showroom/ galleries 

• Restaurant

• Pet shop/pet grooming

• Banks, adjoining or independent ATM clusters

• Commercial school

• Childcare centre/kindergarten

• Gym/fitness centre

• Visitor Centre/ museum

• Hotel/ Backpackers’ hostel

• Self-service laundry

The following uses are not AGUs:

• Office

• Bar

• Nightclub

• Massage establishment

• LAN gaming centre

To maintain the integrity and aesthetics of the waterfront areas so that the public can have free and unrestricted access to enjoy these spaces, developments at major waterbodies¹ shall observe the design and development application submission guidelines below.

¹ Major waterbodies: rivers, canals of at least 17.5m width, reservoirs, and seas.

1. Retaining Walls

   Retaining walls along the waterbodies may be allowed subject to the following criteria:

   1. Retaining walls are less than 1.5m in height;

² Drainage Reserve (DR): An area safeguarded for purposes of building or widening a public drain

The design guidelines listed above shall apply to all developments adjacent to or with waterbodies except developments adjacent to or with Drainage Reserves less than 17.5m.

All proposals involving waterbodies shall comply with the development application submission guidelines listed above.

For land use planning and development control purposes, the foreshore³ and the area within 15m on both the landward and seaward side of the foreshore line⁴ shall be kept free of structures. Some structures such as ramps may be permitted if they are constructed in connection with an approved development (eg marine industries, refineries, and pleasure-boat storage complex). These structures are subject to planning evaluation depending on merits.

³ The area between the high water mark of the Spring Tide or the top of the seawall and the low water mark of the Spring Tide.

⁴ The high water mark of the Spring Tide; the top of the existing seawall or revertment or river wall (where appropriate) for controlling landward development.

Ancillary structures are minor structures erected to support the main use of the site. The building setback distance and height control for ancillary structures are shown in the table below.

Ancillary structures located within the green buffer may be assessed in accordance with NPARKS' guidelines – see here.

Ancillary structures located within the physical buffer and building setback that exceed the requirements in the table below, but are below 6m in height, shall be evaluated depending on the merits of the design and function.

Setback and Height Control for Ancillary Structures

LTA prescribes the parking provision standards and requirements for motor vehicles and bicycles. The requirements are usually based on the quantum of the gross floor area or the number of units of the development uses.

Separately, to enhance commuter experience and reduce congestion at Pick-up and Drop-off Points (PUDOs), LTA and URA collaborated with the industry to develop a design guide for PUDOs containing best practices that building owners and professionals can consider applying to new and existing PUDOs.

Under LTA’s Range-based Parking Provision Standards (RPPS), developments are subject to car and motor-cycle¹ parking provision requirements.

Unless explicitly approved as private parking lots in the approved plans, all car and motor-cycle parking lots shall be treated as common property.

¹ Motor-cycle parking provision is mandatory in all non-residential developments.

The RPPS allows developments to provide any level of car and motor-cycle parking provision within a specified range, defined by a lower bound and an upper bound – see figure below. The range varies according to location zones and land uses. Details may be found in LTA’s Code of Practice for Vehicle Parking Provision in Developments.

New EI developments shall be subject to a process of waiver evaluation by LTA, if one wishes to provide surplus car and motor-cycle parking lots, ie parking provision above the upper bound based on the new RPPS.

Primary/Secondary Schools shall share their school fields and ISHs with the wider community. Separate and independent pedestrian access to the school field and ISHs shall be provided in addition to the normal vehicular and pedestrian access for the school.

For fields, there shall be a clear demarcation from the main school buildings so that the field could be fenced up and opened to the community outside of school hours. The field and the ISH shall both be maintained by the school.

In the design and location of fields and ISHs, the surrounding environment shall be taken into consideration to minimize dis-amenity arising from activities.

For institutions of higher learning (universities, polytechnics) such as SIM, NAFA, LASALLE and INSEAD, the maximum (upper bound) allowable commercial use is 5% of the total proposed GFA or 30,000sqm, whichever is lower.

Examples of commercial uses within EI developments include food courts, restaurants, cafes, book & stationery shops, hair salons, minimarts, banks, travel agencies, medical clinics, student-run businesses.

RC flat roofs shall remain inaccessible except for maintenance purposes only¹. Activating the rooftop for uses such as roof terraces and landscaped gardens may be allowed depending on the merits of the proposal. No structures shall be allowed unless otherwise approved by URA. Where allowed, structures (including any safety barriers) shall comply with height controls² and the following guidelines.

¹ RC flat roofs that are accessible via ladders for maintenance purposes only are subject to agencies’ requirements for safety barriers to ensure the safety of maintenance personnel. Safety barriers shall not exceed 1m in height.

² Height controls applicable, include:

• Absolute technical height constraints^@ (e.g. Aviation paths restrictions, military and telecommunications installations).

• Conservation guidelines (available at URA SPACE)

• Urban design height controls (available at URA SPACE)

^@ The absolute technical height (Based on Singapore Height Datum [SHD]) shall take precedence if it is stricter than any of the other height controls.

Communal pavilions are small-scale, ancillary landscaping features that function as sheltered, open-sided resting points. Access to communal pavilions shall be from common areas only. The pavilions shall be computed as GFA unless they meet the following criteria:

• Maximum 500sqm¹ or 50% of roof coverage, whichever is lower.

• For developments which have reached the allowable storey height control, the pavilions shall remain open-sided when viewed externally. This is to ensure that the pavilions do not form an additional storey.

• For developments which have not reached the allowable storey height or are not located within areas subject to storey height control, maximum 50% perimeter enclosure of the rooftop pavilions may be allowed.

• Communal pavilions shall be integrated with lush greenery. The greenery on the rooftop shall be both enjoyable by the building users and visible from the surroundings.

• Plants shall be incorporated on permanent and preferably sunken planting, planned with sufficient soil depth based on the types of plants proposed. Some space shall be set aside for the provision of communal facilities and furniture to enhance the rooftop.

• A Landscape Plan and relevant sections for ground/rooftop spaces containing communal pavilions, showing the proposed landscaping scheme, pavilion dimensions, planting palette, soil depth, communal facilities, shall be submitted with the Development Application.

¹ The area is defined as the area of pavilion measured up to the roof eaves line.

The installation of solar panels on RC flat roofs may be considered if they meet the following criteria:

1. Solar panels are installed between 10 to 15 degrees relative to the horizontal plane to optimise the performance of solar panels and minimise glare to the buildings in the vicinity; and

2. The installation of solar panels shall not result in the removal of any greenery approved under the Landscaping for Urban Spaces and High-Rises (LUSH) Programme.

Installation of solar panels and M&E equipment such as inverters for the solar panel system does not require planning permission except in locations and contexts described below.

1. Areas subject to urban design guidelines and Conservation Areas² shall require planning permission due to their impact on the roofscape.
   
   ² For Conservation Areas, installation of solar panels without any additional works are treated as localised works for the purpose of repair and maintenance and are considered Category 3 works for Conserved Buildings. Applications for such Category 3 works can be made by owners and contractors. Refer to the Conservation Guidelines here and information on submission procedure here.

2. Elevated solar panels³ located in developments on the following land use zones shall require planning permission:

³ A solar panel is deemed to be elevated if it is raised more than 1m from the roof level for landed housing developments or 1.8m from the roof level for other developments.

3. Spaces under solar panels are enclosed or put to commercial use
   Planning permission shall be required if the spaces under elevated or non-elevated solar panels are enclosed or put to commercial uses such as Outdoor Refreshment Areas. In such instances, the spaces shall be computed as GFA.

Elevated solar panels that require planning permission may be assessed as an additional storey for storey height control purposes unless they comply with the guidelines below:

Guidelines for Elevated Solar Panels

LUSH is a comprehensive urban and skyrise greening programme comprising both Landscape Replacement Areas (LRA) requirements and incentives to provide greenery and communal spaces.

The LRA requirements are calibrated by location, GPR and development type. A development may count Sky Terraces, Communal Planter Boxes and Covered Communal Ground Gardens (see Greenery sub-tabs) amongst other features, towards meeting the LRA requirement.

Applicants may refer to the following self-help checklists for the applicable greenery requirements and information to be submitted for assessment: for private developments here and public sector developments here.

Developments in identified Strategic Areas shall provide LRA that is minimally equivalent to the development’s gross site area, as shown in the table and diagram below. At least 40% of the LRA requirement shall be reserved for softscape (permanent planting) areas. The remaining LRA requirement may be provided as hardscape.

The Green Plot Ratio (GnPR) provides an objective measure of the density of greenery within a site. The formula for computing GnPR and the minimum GnPR requirement is as follows:

The Total Leaf Area shall be computed based on the Leaf Area Index (LAI) for each plant species, canopy area (for trees and palms) and the quantity planted. The plant species sub-categories and LAI values may be obtained online from NParks’ Flora Fauna Web by searching the common or scientific names of plants.

LRA Requirements for Developments in Strategic Areas

¹ Building height is based on Singapore Height Datum (SHD).

The Strategic Areas are as follows:

• Within Central Area: Downtown Core (part), Straits View (part), Marina South, and Orchard (part) Planning Areas, as well as 2 mixed-use parcels along Orchard Boulevard in Paterson Hill Subzone (see Plan 1-1);

• Outside of Central Area: Regional Centres and Growth Areas including the Jurong Lake District, Kallang Riverside, Woodlands Regional Centre, Punggol Creative Cluster, Tampines Regional Centre and Paya Lebar Central as well as commercial and commercial/residential developments within Town Centres (see Plans 1-2 to 1-26).

List of Strategic Areas

 The LRA requirement is not applicable to conserved buildings in historic conservation areas. URA may exercise flexibility on LRA requirements when evaluating individual developments affected by specific constraints.

The table below shows the guidelines for computation of LRAs in Strategic Areas. LRA in Strategic Areas is the sum of:

• Horizontal surface area of the softscape eg permanent planting beds;

• Horizontal surface area of the hardscape eg communal facilities, urban farm; and

• Vertical surface area of green walls and extensive green roofs (if any).

Guidelines for LRAs in Strategic Areas

A Landscape Plan for all Landscape Replacement Areas shall be submitted together with the Development Application, as illustrated below.

The plans shall include:

• Relevant plans, cross sections and perspectives with layouts of the softscape and hardscape areas. The softscape and hardscape areas shall be visually differentiated on plans with the following details:

  • Computations of the overall LRA, softscape areas and Green Plot Ratio;

  • Proposed schedule and annotation of plant species and paving materials;

  • Where relevant, annotations of ancillary uses e.g. Swimming Pool, BBQ Area, etc.;

  • Where relevant, annotations of the 45-degree line;

  • Short statement on the proposed maintenance and irrigation methods for the planting.

Label and package the landscape plans and sections separately from the rest of the floor plans, and separate the softscape and hardscape areas into different layers.

URA’s approval is required if there are changes to the softscape areas (eg planting and structure of the planting beds) and hardscape areas that result in an overall reduction in area for the required LRAs.

URA’s approval is not required for changes to the planting species as long as the softscape and Green Plot Ratio requirements are complied with.

The following table for GnPR computation shall be filled in and submitted together with the landscape plans.

Green Plot Ratio Computation Template

Beyond the various LUSH requirements, building owners and developers are strongly encouraged to adopt the following good practices in their landscape designs to further integrate nature into the urban environment:

Building owners and developers should also continue to exercise care in their landscaping design, including the curation of the planting palette. For example, selection of specific plant species that minimises attraction of pests.

The following incentive schemes can be used throughout the development to provide greenery and communal spaces.

Sky terraces are communal garden spaces provided at the intermediate storeys of a building.

To qualify for GFA exemption, sky terraces shall comply with the criteria in the following table.

Communal planter boxes shall comply with the following criteria:

• Maximum width of 1m;

• Minimum depth of 500mm (for planting purpose);

• To be sufficiently externalized.

Communal planter boxes which are more than 1.0m wide may be allowed if the wider planter boxes are part of an overall scheme with design merit.

Details of the communal planter boxes, including planting palette, spot sections showing soil depth, and dimensions shall be provided as part of the storey plans.

Communal planter boxes shall be designed with safety and maintainability provisions in mind.

Covered Communal Ground Gardens (C2G2) are on-ground greenery spaces at the 1^st storey. The garden should flow seamlessly between the covered and uncovered spaces of the 1^st storey and designed to be bright and airy with quality landscaping. There are two types of C2G2:

1. Predominant C2G2s shall occupy at least 50% of the first storey building footprint. Within the covered garden area, a minimum of 60% shall be lushly landscaped, while the remaining 40% can be set aside for meaningful communal gathering and activity spaces, and unenclosed communal facilities. These spaces may include garden paths, playgrounds, and covered pools. Covered drop-off points may be considered as part of the C2G2 if well-integrated, paved with appropriate material and integrated with lush landscaping.

2. Secondary C2G2 are communal landscaped areas on the 1^st storey which are shaded by a structure or a floor or overhang above. These may be exempted from GFA computation up to a maximum area defined by a 45-degree line taken from the edge of the overhead projection. The GFA-exempted communal areas within the 45-degree line shall contain quality lush landscaping with a variety of vegetation.

All areas of C2G2 spaces shall be easily accessible to the public and/or building users during normal opening hours for the development. The communal ground garden shall not be easily enclosed and converted to any other uses in the future.

For GFA exemption for C2G2, refer to the GFA handbook. URA will assess the C2G2’s design, spatial quality and overall integration with the wider landscaping scheme in considering the proposal’s eligibility for GFA exemption.

A landscape plan shall be submitted as part of the Development Application for the predominant covered ground garden proposal, showing the proposed landscaping scheme.

Communal pavilions are small-scale, ancillary landscaping features that function as sheltered, open-sided resting points. Access to the pavilions shall be from the common areas only.

In addition to being sited within lushly landscaped areas, they shall satisfy the criteria below to qualify for GFA exemption:

Guidelines for Communal Pavilions

A Landscape Plan and relevant sections for ground/rooftop spaces containing communal pavilions, showing the proposed landscaping scheme, pavilion dimensions, planting palette, soil depth, communal facilities, shall be submitted with the Development Application.

EI developments with expected high pedestrian and cyclist traffic are required to provide a WCP as part of the Development Application. As a guide, development types listed in the table below are subject to WCP requirement.

Development Types that require WCP as part of TIA¹

Developments not listed in the table above may also be required to submit a WCP if they fall under the following criteria:

• Developments located in car-lite precincts⁴; or

• Developments located within 400m of major transport nodes, ie within Zone 2⁵; or

• Retail, Office, Mixed Use developments.

Applicants for developments meeting the above criteria are strongly encouraged to check in early with LTA for the requirement of a WCP. See the diagram below for the submission flowchart to LTA and URA.

¹ Developments that have a master developer, and consist of two or more plots that staged at different time will also be required to submit a WCP at the concept design stage.

² LTA and URA will work with HDB on the WCP requirements.

³ Only industrial developments located within car-lite precincts or 400m of major transport nodes ie within Zone 2, will be required to submit a WCP.

⁴ The five car-lite precincts are Bayshore, Jurong Lake District, Kampong Bugis, Marina South and Woodlands North.

⁵ Zone 2 as defined in the Zonal Car Parking requirement in the Code of Practice on Vehicle Parking Provision in Development proposals. Please refer to LTA's website for more details.

The WCP shall consider the safety, convenience, and accessibility of pedestrians and cyclists, and incorporate the following elements in the design of the development:

• Provision of convenient and direct access from nearby public transport facilities and adjacent developments;

• Provision of measures to minimise conflicts between pedestrians, cyclists and motor vehicles at locations such as the vehicular ingress/egress, car park entrances, and drop-off points;

• Provision of sufficient and conveniently located bicycle parking spaces and supporting amenities such as shower facilities and lockers;

• Provision of way-finding signage to public transport facilities and amenities for cyclists; and

• Provision of barrier-free access and routes for children, elderly and the mobility challenged groups.

The detailed guidelines on WCP and submission requirements are summarised in LTA’s Code of Practice “Street Work Proposals Relating to Development Works” via LTA's website.

To provide assistance on developing active mobility-related infrastructure in a holistic manner, a Walking & Cycling Design Guide has been produced as a supplement to the respective agencies’ prevailing COPs, engineering and development standards. The Guide can be downloaded via LTA's website.

Earthworks are defined as any operations or works in, on, or over land which result in substantial modification to the existing ground terrain, land form, or slope. These include excavation, formation of a new slope or embankment, and cut and fill operations.

Extensive earthworks are discouraged as it may change the existing terrain. Earthworks may also result in the building of high retaining walls that mar the streetscape and have adverse impacts on the surrounding areas. Earthworks on any development site, where necessary, shall be minimised.

Planning permission is required if earthworks involve more than 2,000sqm of land or change in the level of the land of more than 1.5m anywhere in the development site or relative to the neighbouring land.

The guidelines for earthworks are dependent on where the earthworks are carried out.

Earthworks may not be allowed within the building setback area, except in the following circumstances:

• When the proposed earthworks are to match the existing platform levels of the neighbouring sites;

• When the sites are on undulating or sloping terrain, with large differences in platform levels within the site, or between the site and the road;

• When the earthcut is necessary to build a fully submerged basement. The area within the building setback shall be reinstated to the original platform level upon the completion of the basement.

Earthworks within the build-able area of more than 1m are subject to evaluation depending on merits. If the earthfill of more than 1m is allowed, the earthfilled area shall not be counted as an additional storey provided the overall aggregate building height complies with the maximum allowable building height measured from the allowable platform level.

Earthfill involving the entire development site may only be considered if the proposed earthworks are required to meet the technical requirements of PUB. Such earthfill may be allowed up to the Minimum Platform Level (MPL)¹ stipulated by PUB.

¹ Minimum Platform Level (MPL): The minimum 1^st storey level to be provided within the site. The MPL is determined by the Public Utilities Board (PUB).

The maximum allowable height for boundary walls is 1.8m.

High retaining walls shall be avoided wherever possible, particularly for small in-fill plots. If they have to be built and can be allowed, they shall meet the following requirements:

• the height shall be less than 1.5m;

• retaining walls higher than 1.5m may be considered due to site constraints and the need for extensive excavation;

• the total visible height of the solid boundary-cum-retaining wall shall not exceed 2.8m, of which the solid boundary wall shall not exceed 1.8m.

If the retaining walls are to meet the MPL requirement stipulated by PUB for drainage purposes, the retaining walls along the site boundaries (except along boundaries that abut foreshore, roads, or waterbodies with drainage reserve equal to or more than 17.5m wide) need not be tiered as these are transitory, pending the redevelopment of the neighbouring land to the same MPL.
